WOVEN FABRIC.

Specification 01 Letters Patent.

Patented June 29, 1909.

Application filed January 2, 1908. Serial No. 408,889.

T 0 all whom it may concern:

Be it known that we, Josnrn Pn'rnn Znrr and ALBERT E. Connrr-mnn, ot thecity of Peter-borough, in the county 01 Peterborough and Province ofOntario, Canada, have invented certain new and useful Improvements inWoven Fabrics; and we hereby declare that the following is a full,clear, and exact description of the same.

This invention relates to a woven fabric having two separate sets ofwarp threads with one set constantly overlying the other set, and a setof wet't threads woven through the warp threads so that each set of warpthreads can be used to produce a face for the woven fabric without oneset 01? warp threads being visible through the other set of warp threadsexcept when the position of the warp threads is reversed to form thepattern in the fabric.

In the production of the woven fabric according to this invention oneset of warp threads may be of one color, quality, or, material, and theother set of warp threads may be of a different color, quality, or.material, with the two sets 01'' warp threads kept on their respectivesides of the woven fabric without the warp threads of one set showingthrough the warp threads or the other set except when their positionsare intentionally altered by the action of the loom to produce thefigure or pattern in the weave, as hereinafter set forth and pointed outin the claims.

For an understanding of the invention reference is to be had to theFollowing description and to the accompanying drawings in which 2 Figure1, is a longitudinal section showing in a conventional manner thedisposition 01 several 'arp and weft threads. Fig. 2, is a similar viewto Fig. 1, showing the arrangement of a pair of warp threads, that is ataco warp thread and its corresponding back warp thread and the weftthreads. Fig. 3, is a plan View of a pattern paper from which theacquard cards are prepared the dots and dashes on the pattern papersindicating the manner in which the acquard cards are to be punched.

Like characters of reference refer to like parts throughout thespecification and drawmgs.

The woven fabric as shown in Fig. 1, consists of two sets of warpthreads and one set of weft threads. One set of warp threads overliesthe other set of warp threads and in 2t), 27, 28, under 211,

weaving the fabric, each set of warp threads is continually maintainedon its respective side of the fabric as the warp threads pass over andunder the weft threads so that each set of warp threads will form itsrespective l -ace oi the fabric without the other set of warp threadsappearing therein, except when the normal position of the warp threadsis altered to form the pattern. For convenience of description the oneset of warp threads which may be of one color, quality, or material, arelettered by the letters a, I), c, d, and c. The other set ot warpthreads which may be of any other color, quality, or material, arelettered f, g, h, 2', and The we'l't threads are numbered from 1 to 31inclusive. 1n weaving the fabric the warp thread (1 passes under theweft threads 1 and 2, over 3, :1, 5, t3, 1, 8, 5), 10, under 11., over12, 13, 11, 15, 1(3, 17, 18, 19, 20, under 21, 22, over 23, 2 1;, 25,26, 27, 28, 2t), 30, under 31. The warp thread Z) passes over 1, 2, 3,-1-, under 5, over (5, T, S, t), 10, 11, 12, 13, .1-1, nnd r 15, 16,over 17, 18, 1t), 20, 21, 22, 23, 21, under over 213, 27, 2C, 25), 30,and 31. The warp thread 0 passes over 1, 2, 3, 1, 5, (3, T, 8, under 9,10, over 11, 12, 123, 11, 1.5, 16, 17, 18, under 15), over 20, 21, 22,223, 2-1, 30, over 31.. The warp thread passes over 1 and 2, under 3 and4-, over 5, n, 7, 8, 9, 10, 11, 12, under 13, over 1-1, 15, 1(3, 17, 18,1t), 20, 21, and 22, under 23, and 21, over 25, 26, 27, 28, 2t), 30, and3. The warp thread 0 passes over 1, 2, 3, 1, 5, (3, under T, over 8, f),10, 11, 12, 13, 11, 15, and 16, under 17 and 18, over 11), 20, 21, 22,23, 2-1, 25, and 213, under 27, over 28, 2t), 3t), and 31. The warpthread j lies below the warp thread (t and passes under 1, 2, 3, over{1, under 5, (3, 7, S, t), 10, 11, 12, 13, over 11, under 15, 1o, 17,18, 19, 20, 21, 22, 2;), over 21, under 25, 213, 27, 28, 29, 30, and 31.The warp thread g lies below the warp thread 7) and passes under 1, 2,3, 1, 5, (3, 7, over 8, under 1), 10, 11, 12, 13, let, 15, 113, and 17,over 18, under 12), 20, 21, 22, 23, 241-, 25, 2G, 27, over 28, under 29,30, and 31. The warp thread 71. lies below the warp thread 0 and passesunder 1, over 2, under 3, 4r, 5, (3, 7, 8, 9, 10, 11, over 12, under 13,1-1, 15, 1(3, 17, 18, 19, 20, 21, over 22, under 23, 2-1, 25, 2(3, 27,28, 2t), 30, and 31. The warp thread 2' lies below the warp thread (Zand passes under 1, 2, 3, 41-, 5, over (3, under 7, S, t), 10, 11, 12,13, 1-1, 15, over 16, under 17, 18, 1t), 20, 21, 22, 23, 2-1, and 25,over 26, under 27,

28, 29, 30, and 31. The warp thread 7' lies below the warp thread 6 andpasses under 1, 2, 3, 4, 5, 6, 7, 8, 9, over 10, under 11, 12, 13, 14-,15, 16, 17, 18, 19, over 20, under 21, 22, 23, 24:, 25, 26, 27, 28, 29,over 30, and under 31.

By reference to the drawings it will be seen that where the warp threada crosses under a wettthread, that the warp thread 7" flows under it,and that when the warp thread f crosses over a wett thread, the warpthread a floats over the crossing. The same remarks are also applicableto the warp threads Z) and c and 7b, (Z and 2', and (2 and j.

Having thus fully described our invention what we claim as new anddesire to secure by Letters Patent is l. A woven fabric comprising twoseparate sets of warp threads with one set of warp threads continuallyoverlying the other set of warp threads, and a single set of weftthreads woven through the tabrie tain the sets of warp threadscontinually in juxtaposition so that the warp threads of 25 one set willnot show through the warp threads or the other set.

2. A woven fabric comprising two separate grounds, each formed or" asingle set of warp threads, and a single set of weft threads containedbetween and alternately engaging the warp threads of the two grounds,the warp threads of each ground overlying the tying weft threads andseveral adjoining weft threads where they pass 35 through the warpthreads of the other ground.
